Embodiment 1

[0043] Such as figure 1 As shown in the process flow, the glucose-fructose syrup, dietary fiber, antioxidant active parts and anti-tumor active parts of wild jujube are prepared by the following method:

[0044] (1) Dry the spiny jujube pulp after preparing the spiny jujube kernels in a hot air circulation oven at 50°C. The dried spiny jujube pulp is cooled and crushed. Take 10 kg of the crushed spiny jujube pulp powder and add 100 kg of 80% ethanol for reflux extraction for three times. Each time for 1 hour, the extracts were combined and filtered to obtain the ethanol extract and ethanol extraction residue.

[0045] (2) Take the alcohol extraction residue obtained in step (1), centrifuge to separate the residual solvent, dry it in a hot air oven, crush it through a 60-mesh sieve, and obtain about 3 kg of jujube dietary fiber powder, which is sieved and pressed into 1 g jujube Dietary cellulose tablet, its main components are: soluble jujube polysaccharide (32%), cellulose ...

Embodiment 2

[0051] The preparation method of jujube fructose syrup, dietary fiber, antioxidant active fraction and antitumor active fraction specifically comprises the following steps:

[0052] (1) Dry the spiny jujube pulp after preparing wild jujube kernels in a hot air circulation oven at 50°C, and then crush the dried spiny jujube pulp after cooling. Take 10 kg of crushed spiny jujube pulp powder and add 60% ethanol for percolation, and collect the percolation liquid for 240 kg and the residue after percolation.

[0053] (2) Take the residue after percolation obtained in step (1), centrifuge to separate the residual solvent, dry it in a hot air oven, crush it through a 60-mesh sieve, and obtain about 2.9 kg of jujube dietary fiber powder, which is sieved and pressed into 1 g Jujube dietary cellulose tablets, its main components are: soluble jujube polysaccharide (34%), cellulose (40%), crude protein (15%).

[0054] (3) Take the ethanol extract obtained in step (1) and concentrate und...

Embodiment 3

[0059] The preparation method of jujube fructose syrup, dietary fiber, antioxidant active fraction and antitumor active fraction specifically comprises the following steps:

[0060] (1) Dry the spiny jujube pulp after preparing wild jujube kernels in a hot air circulation oven at 50°C. The dried spiny jujube pulp is cooled and crushed. Take 10 kg of crushed spiny jujube pulp powder and add 70% ethanol to extract continuously under the condition of 50°C. , collect 260 kg of extract and residue after extraction.

[0061] (2) Take the residue obtained in step (1), pressurize and filter to separate the residual solvent, dry the residue in a hot air oven, pulverize and pass through a 60-mesh sieve to obtain about 3.3 kg of jujube dietary fiber powder, which is sieved and pressed into 1 g Jujube dietary cellulose tablets, its main components are: soluble jujube polysaccharide (30%), cellulose (41%), crude protein (12%).

[0062] (3) Take the ethanol extract obtained in step (1) and...

Abstract

The invention discloses the high fructose corn syrup, the dietary fiber, the anti-oxidation active parts and the anti-tumor active parts of wild jujube as well as a preparation method and application thereof. The preparation method comprises the following steps of: taking the flesh of wild jujube as a raw material, extracting by ethanol and preparing residues into the dietary fiber powder of the wild jujube; separating an alcohol extract by macroporous resin, eluting by using water and ethanol with different concentrations sequentially, and washing eluent by the water so as to obtain the high fructose corn syrup of the wild jujube; and washing the eluent by ethanol with low concentration so as to obtain the anti-oxidation active parts, washing the eluent by ethanol with high concentration, adding a low-polarity organic solvent and extracting so as to obtain the anti-tumor active parts of the wild jujube. According to the preparation method, the flesh of waste wild jujube is utilized as the raw material, the active components of the wild jujube are extracted by a method combining a modern extracting and separating means and pharmacological activity sieving, wastes are changed into valuables, and various free radicals can be removed by the anti-oxidation active parts in the hope of being developed into a medicine for oxidation resistance and senescence resistance; and the anti-tumor effective parts have clearer active components and high content, have very good functions of suppressing and killing various tumor cells and are in the hope of being developed into a novel anti-tumor medicine.

Description

technical field [0001] The invention relates to an active ingredient of a plant fruit and an extraction technology thereof, in particular to a jujube pulp glucose-fructose syrup, dietary fiber, anti-oxidation active parts and anti-tumor active parts and a preparation method and application thereof. Background technique: [0002] Jujube ( Ziziphus jujuba var. spinosa ) is a plant of the genus Jujube in the family Rhamnaceae (Rhamnaceae), widely distributed in the vast areas of northern my country, and its mature fruits contain a variety of bioactive components, such as glucose, fructose, plant polysaccharides, betulinic acid, oleanolic acid, bearberry Acid, etc., has multiple pharmacological effects, and is a unique biological resource in my country. Its dry and mature seeds, Suanzaoren, are commonly used in traditional Chinese medicine. They have the effects of nourishing the heart and nourishing the liver, calming the mind, relieving sweat, and promoting body fluid. A...
